  1. 1. Abrasionsmekanismer i labtest och fält : Utvärdering av metoder för nötningsprovning av spetsar till pinnkultivatorer

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Clara Landström; [2022]
    Nyckelord :tribologi; materialvetenskap; abrasiv nötning;

    Sammanfattning : In this master thesis two simplified and small-scale methods for two-body and three-body abrasive wear were examined. It was examined how representative the methods were compared to field-tested points in a cultivator for agriculture. A total of six points with different compositions were tested and ranked based on the test results. LÄS MER

  3. 2. Effect of gritting sand quality on road dust pollution

    Master-uppsats, KTH/Vägtekniks laboratorium

    Författare :Octavian Babiuc; [2016]
    Nyckelord :Pollution; road dust; particulate matter; gritting sand; studded tires; resistance to abrasion;

    Sammanfattning : Pollution of air represents the contamination with matter that can affect both humanhealth and the environment. Road dust has been recognized as a dominant source ofparticulate matter and one of the factors that contributes to its development is the useof gritting sand. LÄS MER

  4. 3. Durability of Superhydrophobic Coatings - Sand Abrasion Test

    Kandidat-uppsats,

    Författare :Max Holmberg; Hugo Harlin; [2016]
    Nyckelord :Superhydrophobic; hydrophobic; contact angle; durability of superhydrphobic coatings; sand abrasion;

    Sammanfattning : The interest in superhydrophobic coatings have increased exponentially in the recentdecades due to their potential and versatility in their applications. The use forsuperhydrophobic surfaces range from water repellent fabric, to self cleaning surfacesand numerous applications in industry. LÄS MER

  5. 4. Wear testing of high-alloy carbon steel used in mining tools

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Sara Olsson; Linn Efsing; [2013]
    Nyckelord :Wear; Wear-testing methods; Adhesive wear; Abrasive wear; Nötning; Nötningstester; Adhesiv nötning; Abrasiv nötning;

    Sammanfattning : Wear is a commonly occurring degradation mechanism for materials and components in the rock drilling industry. The wear can occur by either abrasion or adhesive wear. Further corrosion and presence of water or other lubricating fluids with or without particles may influence the behavior. LÄS MER

  7. 5. Accelerated aging of thick glass second surface silvered reflectors under sandstorm conditions

    Master-uppsats, Maskinteknik

    Författare :Simon Caron; [2011]
    Nyckelord :Accelerated aging; Sandstorm simulation; Solar Energy;

    Sammanfattning : Concentrated solar power systems are expected to be sited in desert locations where the direct normal irradiation is above 1800 kWh/m2.year. These systems include large solar collector assemblies, which account for a significant share of the investment cost. LÄS MER
